However, existing handle structures often occupy valuable internal space in the battery compartment, resulting in reduced space utilization. While simple handle solutions such as soft ropes can be used under the current strict space constraints of electric vehicles, these external handle designs still have significant drawbacks: firstly, exposed handles may mechanically collide with the side walls of the battery compartment; secondly, there is a risk of the handle becoming entangled or tripping over the user. Utility Model Content
[0003] The purpose of this utility model is to provide a battery handle mechanism, a battery, and an electric vehicle to alleviate the technical problem of exposed battery handles in the prior art.

[0011] A limiting part is provided between the embedded groove and the mounting groove, and the lifting member slides through the limiting part and is connected to the elastic member;
[0012] The elastic force of the elastic element acts on the lifting element, causing the lifting element to pull the handle to retract into the inner groove.
[0013] In conjunction with the second possible implementation of the first aspect, the present invention provides a third possible implementation of the first aspect, wherein a clamping member is sleeved on the end of the lifting member extending into the mounting groove;
[0014] The elastic element is sleeved on the lifting element, and the elastic element is compressed between the clamping element and the limiting part.

[0022] The present invention provides the following advantages: A housing with an inner groove and a mounting groove is used, with the mounting groove located below the inner groove. A handle extends from the inner groove into the mounting groove. An elastic element is installed in the mounting groove and connected to the handle. The elastic element tends to pull the handle into the mounting groove and embed it into the inner groove. Pulling the handle upwards can pull the battery handle mechanism out of the inner groove, facilitating battery handling. After releasing the handle, the elastic element allows the handle to retract into the mounting groove, embedding its top into the inner groove. This avoids the handle being exposed and occupying battery compartment space, improving battery compartment energy density and preventing collisions between the exposed handle and the inner wall of the battery compartment.

[0033] like Figure 1 As shown, the battery handle mechanism provided in this embodiment of the present invention includes: a handle 100, an elastic member 200, and a housing 300; the housing 300 is provided with an inner groove 301 and a mounting groove 302 located below the inner groove 301; the handle 100 extends from the inner groove 301 into the mounting groove 302; the elastic member 200 is installed in the mounting groove 302 and connected to the handle 100; when the handle 100 is pulled out of the inner groove 301, the elastic member 200 has a tendency to pull the handle 100 into the mounting groove 302 and embed the handle 100 into the inner groove 301.
[0034] In an optional embodiment, one end of the elastic element 200 can be connected to the housing 300, and the other end can be connected to the handle 100. When the handle 100 is lifted upward, the elastic element 200 is compressed or stretched to achieve elastic deformation, and the handle 100 is pulled outward from the inner groove 301; when the handle 100 is released, the elastic element 200 rebounds, thereby causing the elastic element 200 to retract into the inner groove 301. Specifically, the elastic element 200 can be a tension spring, with one end connected to the bottom of the mounting groove 302 and the other end connected to the handle 100. The elastic contraction of the tension spring causes the handle 100 to retract from top to bottom into the inner groove 301. The elastic element 200 may also be a compression spring, which is sleeved on the handle 100 extending into the mounting groove 302. The compression spring is compressed between the limiting part 303 at the top of the mounting groove 302 and the clamping part 400 at the bottom of the handle 100. By the spring rebounding and elongating, the handle 120 at the top of the handle 100 is pulled back into the recessed groove 301.
[0035] In an optional embodiment, the recessed groove 301 and the mounting groove 302 are spaced apart. The handle 100 and the elastic member 200 can be connected by a pull wire or a soft rope. The pull wire or soft rope can extend from the recessed groove 301 through the outside of the side of the housing 300 into the mounting groove 302.
[0036] In this embodiment, a limiting part 303 is provided between the inner groove 301 and the mounting groove 302. The limiting part 303 is provided with a hole. The handle 100 can slide through the hole on the limiting part 303 from the inner groove 301 and extend into the mounting groove 302, so that the elastic force of the elastic member 200 can directly act on the handle 100, and the protruding device on the side of the housing 300 can be avoided.
[0037] In this embodiment of the present invention, when the handle 100 is embedded in the inner groove 301, the elastic member 200 has a tendency to pull the handle 100 into the inner groove 301.
[0038] Since the handle 100 is always kept taut by the elastic element 200, after the battery handle mechanism is installed in the battery compartment of the electric vehicle, the handle 100 can be kept stable even when the electric vehicle is driving on a bumpy road, thus effectively avoiding noise caused by the loose handle 100.
[0039] In addition, in the embodiment where the handle 100 passes through the hole on the limiting part 303 and is connected to the elastic member 200, the elastic member 200, which keeps the handle 100 taut, can also prevent the handle 100 extending into the mounting groove 302 from swinging, thereby preventing the handle 100 and the elastic member 200 from swinging to the outside of the mounting groove 302.
[0040] In an optional embodiment, a limiting block or similar structure may be provided at the edge of the side opening of the mounting groove 302 to prevent the elastic member 200 and the handle member 100 extending into the mounting groove 302 from swinging outwards from the mounting groove 302.
[0041] like Figure 1 and Figure 2 As shown, in an optional embodiment, the handle 100 includes: a lifting member 110 and a handle 120 connected to the lifting member 110; a limiting part 303 is provided between the inner groove 301 and the mounting groove 302, the lifting member 110 slides through the limiting part 303 and is connected to the elastic member 200; the elastic force of the elastic member 200 acts on the lifting member 110 and causes the lifting member 110 to pull the handle 120 to retract into the inner groove 301.
[0042] The housing 300 may include a cavity shell and a top cover that fits onto the cavity shell. The upper surface of the top cover is recessed from top to bottom to form an inset groove 301, and the outer side wall of the cavity shell is recessed to form a mounting groove 302. The limiting part 303 includes a bottom edge portion on the top cover located below the inset groove 301, and a top edge portion on the cavity shell located above the mounting groove 302. The lifting member 110 passes downward through the bottom edge portion and the top edge portion from the inset groove 301 into the mounting groove 302.
[0043] In one alternative embodiment, the end of the lifting member 110 extending into the mounting groove 302 is fitted with a clamping member 400; the elastic member 200 is fitted onto the lifting member 110, and the elastic member 200 is compressed between the clamping member 400 and the limiting portion 303.
[0044] The clamping member 400 can be a spring clip, which clamps the lifting member 110, keeping the elastic member 200 between the spring clip and the limiting part 303 and maintaining it in a compressed state. Alternatively, the clamping member 400 can be a metal sleeve. During installation, the metal sleeve is first placed on the end of the lifting member 110 located in the mounting groove 302, keeping the elastic member 200 pressed between the metal sleeve and the limiting part 303. Then, a tool is used to squeeze the metal sleeve radially, reducing its inner diameter and clamping the lifting member 110. To ensure a stable connection between the metal sleeve and the lifting member 110, in embodiments where the lifting member 110 includes a steel wire rope 111, the ends of the steel wire rope 111 can be bent and overlapped. The metal sleeve surrounds and clamps the overlapping steel wire rope, making the connection more stable and reducing the risk of the metal sleeve detaching from the lifting member 110.
[0045] In another alternative implementation, such as Figure 1 and Figure 3 As shown, the end of the lifting member 110 extending into the mounting groove 302 is threaded with an end cap 500; the elastic member 200 is sleeved on the lifting member 110, and the elastic member 200 is compressed between the end cap 500 and the limiting part 303.
[0046] The lifting member 110 extends into the mounting groove 302 and is connected to a screw. An end cap 500 is mounted on the screw. This not only compresses the elastic member 200 between the end cap 500 and the limiting part 303, but also allows the degree of compression of the elastic member 200 to be adjusted by screwing the end cap 500 when the handle 120 is initially retracted into the inner groove 301.
[0047] In alternative implementations, such as Figure 1 and Figure 2 As shown, the lifting component 110 includes a steel wire rope 111 and a rubber coating 112 that wraps around the steel wire rope 111.
[0048] The steel wire rope 111 adopts a multi-strand braided structure, and its overall outer diameter can be configured from 2mm to 4mm. The outer diameter can be configured according to the battery weight, ideally with a smaller diameter sufficient to stably support the battery weight, maximizing space saving and weight reduction. The steel wire rope 111 is wrapped with rubber 112, which on the one hand prevents the exposed steel wire rope 111 from scratching personnel, and on the other hand prevents direct friction between the steel wire rope 111 and the housing 300, thus avoiding frictional damage to the housing 300.
[0049] The lifting member 110 can not only be lifted upwards, but also bend laterally by the handle 120. To make the wire rope 111 more flexible, solid steel wire can be used as raw material and woven into a multi-strand structure.
[0050] In addition, the material of the rubber coating 112 should have a certain rigidity and toughness, and the rubber coating 112 should be able to spring back to an upright state, thereby reducing the resistance of the rubber coating 112 passing through the hole on the limiting part 303. This makes it easier to pull the handle 120 upward, and also ensures that after the handle 120 is released, the elastic element 200 can pull the lifting element 110 to slide smoothly, so that the handle 120 can be reset into the inner groove 301.
[0051] Furthermore, the handle 120 includes a plastic part 121 integrally formed with the overlay 112 by injection molding.
[0052] By using a rubber coating 112 to encase the steel wire rope 111, protection is achieved for the steel wire rope 111, reducing corrosion caused by contact with air and water. Furthermore, a plastic part 121 can be integrally formed with the rubber coating 112 using injection molding. This plastic part 121 can be embedded in the inner groove 301, serving as the retracted state of the handle 120. The plastic part 121 of the handle 120 is injection molded as a single unit with the rubber coating 112, preventing slippage of the handle 120 relative to the lifting member 110 when gripping it, thus improving grip stability. Additionally, grooves for finger engagement can be provided on the plastic part 121 to enhance grip comfort.
[0053] like Figure 1 and Figure 4 As shown, in another optional embodiment, the handle 120 includes a soft rubber sleeve 122 fitted onto the lifting member 110. The soft rubber sleeve 122 covers the part of the lifting member 110 located in the inner groove 301, thereby increasing the gripping area of the handle member 100. This not only avoids hand injuries but also reduces the space occupied by the handle 120, thereby reducing the size of the inner groove 301 and increasing the energy density of the battery.
[0054] like Figure 1 As shown, the battery provided in this embodiment of the present invention includes the battery handle mechanism described in the above embodiments.
[0055] The electric vehicle provided in this embodiment of the present invention is equipped with the battery handle mechanism described in the above embodiments.
[0056] The aforementioned batteries and electric vehicles all possess the technological advantages of battery handle mechanisms, which will not be elaborated upon here.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
